Experience of laparoscopic liver resection for various liver diseases.

Backgrounds/aims: We present our experience of laparoscopic liver resection for various liver diseases.

Methods: From April 2008 to August 2012 in Chungnam National University, 68 of 253 liver resections were performed laparoscopically. During the first year, laparoscopy-assisted liver resection was mainly performed and subsequently totally laparoscopic liver resection was the main operative type. Surgery type for treatment purposes was decided preoperatively. Clinical data were collected retrospectively and analyzed.

Results: Preoperatively, 43 patients (63.2%) were diagnosed with benign disease, 19 patients (27.9%) were malignant liver tumors and 6 patients (8.8%) were indeterminate liver tumor but favorable towards malignancy. Anatomical major liver resection was performed in 58 cases (85.3%) and 10 cases (14.7%) were non-anatomical resection. Left hemihepatectomy was performed in 38 cases (55.8%) followed by left lateral sectionectomy in 18 cases (26.5%), and segment IV and IVa segmentectomy, were each in 1 case. Mean operation time was 235.0 minutes (range, 60-470) and 14 patients (18.6%) had intraoperative transfusion. Mean postoperative hospital stay was 10.2 days (range, 4-32). Mean operation time of laparoscopy-assisted left lobectomy was 317 minutes and totally laparoscopic left lobectomy was 281 minutes, but there was no significant statistical difference between these two operation types. There were 11 episodes of postoperative complications in 8 patients. There was no mortality after laparoscopic liver resection.

Conclusions: We concluded that laparoscopic liver resection is a feasible operation, but needs to be carefully conducted in malignant tumors.
